Sqrt 80n^2 = sqrt 40x2xnxn = sqrt 20x2x2xnxn = sqrt 10x2x2x2xnxn = sqrt 5x2x2x2x2xnxn

Pull out numbers and letters in groups of 2

2x sqrt 5x2x2xnxn
2x2x sqrt 5xnxn
2x2xnx sqrt 5

Multiply the numbers and letters on the outside of the radical

4n x sqrt 5 is the final answer.

A 37 foot board must be cut into two parts. The longer part is one foot larger than the twice the shorter part. How long is each
Rus_ich [418]

Answer:

12 ft  and 25 ft

Step-by-step explanation:

a part is x ft and the other is (2x+1) ft

so 37= x  + 2x+1

   37= 3x+1

  -1        -1

   36= 3x

    :3     :3

   x= 36:3

  I=  x= 12 ft

 II= 2x+1=2*12+1=25 ft

The points (4, 9) and (0, 0) fall on a particular line. What is its equation in slope-intercept form?
Nikolay [14]

Answer:

The equation of the line would be y = 4/9x

Step-by-step explanation:

In order to find the equation, we first need to find the slope. We can do this by using the slope equation with the points.

m(slope) = (y2 - y1)/(x2 - x1)

m = (9 - 0)/(4 - 0)

m = 9/4

Now that we have this, we can use point-slope form along with one of the points to get the equation.

y - y1 = m(x -x1)

y - 0 = 4/9(x - 0)

y = 4/9x

One leg of a triangle has a measure of 24 units if the hypotenuse measures 25 units what is the lengh of the other leg
marusya05 [52]
If we assume this is a right triangle

 for a right triangle
if it has legs length a and b and hyptonouse c then
a²+b²=c²

given
a leg is 24
hyptonuse =25
the other leg is b

24²+b²=25²
576+b²=625
minus 576 from both sides
b²=49
sqrt both sides
b=7

the other leg is 7 units
